TPS22996H-Q1中文资料具有可调上升时间的汽车级双通道 5.5V 4A 14mΩ 负载开关数据手册TI规格书

描述 Description

TPS22996H-Q1 is a dual-channel load switch with controlled turnon. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.6V to 5.5V, and can support a maximum continuous current of 4A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which can interface directly with low-voltage control signals. The device is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switch turns on again when the junction temperature stabilizes to a safe range. The device also offers an integrated 230Ω on-chip load resistor for quick output discharge when the switch is turned off.

The pins of the TPS22996H-Q1 are resistant to high humidity conditions, meaning that the device is able to function with a 100kΩ short from any pin to GND or power.

The TPS22996H-Q1 is available in a small, space-saving 2.1mm × 1.2mm 8-DYC package. The device is characterized for operation over the free-air temperature range of –40°C to 125°C.
